This invention relates to -a combination Weatherstrip and sash balancewhich can be' applied to either old windows or. to new.

An object of. the invention is to provide an improved weather strip andsash balance which after the initial installation can be applied andremoved as desired, thus permitting, the ready removal of the sash forthe purpose'ofcleaning'the outside thereof, and theirreplac-ement'without the use of tools.

A further object of the invention is to provide a weather strip and sashbalance coextensive in length with the depth of the sash'so thatv theweather is completely excluded;

A further object of thelinv'entionis to provide a device of thefcharacter indicated" which will efiectively hold the sash at anyelevatiorias desired.

A further object of the invention is to" provide a device of thecharacter indicated which is economical in manufacture, easy to'ope'rate and highly efficient for the purposes intended."

Further objects will more particularly appear inthe course of thefollowing detailed description.

The invention consists in the novel construction, arrangement andcombinations of parts hereinafter more; particularly described andclaimed. I

One sheet of drawings accompanies this specification aspart thereof, inwhich like reference characters indicatelike partsthroughout'. 1

I In the drawing:

Figure 2 is a fragmentary horizontal cross section taken through thewindow frame and a portion of a sash and the improved strip andsashbalance; 7

c Figure 3 is a vertical cross section taken'on the line-3-3 of Figure2; b 1 Figure 4 is a fragmentary-back plan viewof one end of theimproved weather strip and sash balance; and ,7 1

Figure 5 is a fragmentary perspective'view of the hinged connectionforthearticulated'portions of the weather strip and sash balance.

In the modern construction of homes there are numerous objections to thelong prevalent form of sash controls comprising cords and weights whichhave proven objectionable for many years both by the additional spaceand expense required in the construction of the Window frames Claims.(01. '20.--52 .e) v

to provide. the necessary wells, for the weights, and also 'in thetendency of the? cords to break and .the necessity of. removing"normally permanent parts or the" window frame in "order to gain accessto the weights for the replacement of the'cordsj I The result 'o'fth'ishas been the development of frictional devices and the present inventionis directed to an' 'improved" frictional slide device which can beinterposed between the side edges ofthe' sash a'nfdj'a planar.surface'of the. window frame construction, thereby eliminating entirelythe weight welLaswell as the sash cords; pulleys, et'c., and. providingin one device an efii'cient weather strip andbalance for the sash.

Such frictional devices have been heretofore proposed, but in view ofthe fact that the sash in a normal double sash window are each of adepth in excess of one-half of the total height of'the window openingsby the width of the central rail, such frictional devices havenecessarily been made shorter than the sash, thereby rendering theminefilcient to completely exclude wind and weather. If made of the fulllength of the sash, they could only beinstalled and removedby removal ofthe guide strips? on the a-ame.--

In accordance withthe present'invention the improved weather strip andsash balanceis-made in articulate form so that it can be bent and andthereby permit the insertion of such a weather strip and sash balance'ofthe full length or the sash} notwithstanding the 'fact' that the spaceavailable above the. sash is less than onehalf of the window opening.

Thev improved weather strip and sash weight of which the attacheddrawing discloses an efficient embodiment, comprises two frictionalslide mern-bers. ll, each of whichis preferably beveled on itslongitudinal edges as at 22 to prevent .'the entrance and adherence ofpaint in the normal painting of th'efwindolvwflandeach of whichfrictional stripsisipreferably formed, as illustratedof T-cross secti'onhaving a stem portion 3' adapted to mm a box-like base'member formed ofchannel cross section having its end portions inturned, as at 5 -5, toform such ends. The window sash S are initially formedlwithlongitudinally extending grooves G, and preferably one base section, andits associated slide section, are substantially less'in length than theother base section and its associated slide. section, to

permit the introduction of the combinedmembers with a minimumflofflexing. However, the combined lengths of the two associated basesections and slide sections, are equal to the full length of the grooveG and the sash s. Each of the frictional slide members l-l iscoextensive in length with the respective base members 4-4 and thesecombined base and slide member-s, identified by the characters a and b(Figure are hingedly connected by a flat spring strip 1' adapted to lieflat against the web of the channel member forming the base 4 and to besecured by its ends to said web by the rivets 8. These rivets 8 areformed with heads 11 and with their opposite ends 9 of reduced diameterso that when the ends of the rivet are set, as at I0, they will rigidlyassociate the end of the spring strap 1 with the web of the channelbase, as is well illustrated in Figure 3. The heads I I of the rivets 8are slidable in countersunk holes l2 set in from the outer face of theslide members I, and the leg portion 3 of the slide member is normallyforced away from the web of the channel base by compression springs M, aportion of which is seated in the countersunk holes l3 formed in the leg3 of the slide strip and opening toward the inner face of the web of thechannel base.

By reason of the structure thus far described, it will be apparent thatthe legs 3 of the frictional sections I will be slidable in and out ofthe channel base, being normally'forced outwardly by the compressionsprings M with the outward movement limited by the heads of the bolts 8.

.At the abutting ends of the friction strips [-4 are positioned smallpieces of felt of substantially the thickness of the inturned endportions 55 of the channel base members, so as to provide a completeseal for the two frictional strip members when the same are brought intolongitudinal alignment.

At one end of one section of each weather strip and sash balance isprovided means for securing the channel base members againstlongitudinal movement with respect to the sash, comprising plate 20adapted to bridge the edge of the sash and the adjacent end of thefrictional slide, the plate 20 being bent backward upon itself, as at2!, and thence downwardly, as at 22, within the channel base, having itsend 23 extending through a slot in the web of the channel base to forman outwardly directed lug l8 projecting beyond the outer face of the webIS. The entire channel member is preferably disposed in a groove Gformed in the side edge of the sash and in the base of this groove isdriven a naillike member 5 having a head I! formed with a transversenotch l8.

When properly positioned in the groove G of the sash S, lug l8 engagesthe groove l8 and securely locks the channel base members againstlongitudinal movement with respect to the sash. From a consideration ofFigure 3 it will be apparent that when it is desired to remove theweather strip and sashbalance, that pressure against the edge of plate20 will force the channel member against the pressure of springs I 4toward the frictional slide, thereby permitting the ing 18 to pass outof the slot T8, at which point alignment with the lower section and theentire 4 device inserted and withdrawn, as desired, without the removalof any of the covering strips from the window frame.

Where these improved weather strips and sash balances are used in newconstruction it will be apparent that the structure of the window framesF can be materially simplified and cheapened by eliminating the boxstructure on each side ordinarily provided to house the sash weights.However, the device can readily be used with frames of conventionalstructure, thereby eliminating the use of the cords and weights.

, While the present specification discloses a highly desirableembodiment of the invention, it will be apparent that othermodifications will readily suggest themselves to those skilled in theart, but Within the scope of the present invention as claimed.

Having thus fully described my invention, I
